A voltage reference source (10) comprises a source block (21), a first resistor (16) having a first terminal coupled to a first terminal (22) of the source block (21), a reference output (15) for providing a reference voltage (S6), and a first and a second mirror transistor (11, 12) forming a first current mirror (13). The first mirror transistor (11) couples a second terminal (23) of the source block (21) to a supply voltage terminal (14) and the second mirror transistor (12) couples the reference output (15) to the supply voltage terminal (14). A series connection (17) of a second resistor (18) and a diode (19) is arranged between the reference output (15) and the first terminal of the first resistor (16). A mirror current (S3) flows through the second mirror transistor (12) and the series connection (17) to the first terminal of the first resistor (16). |
